1. Introduction
The SI-R320S and SI-R320 projection systems are system integration solutions combining Sony
Digital Cinema 4K projectors and customised Doremi cinema server technology.
These solutions utilise the SRX-R320S and SRX-R320 projector-only models (i.e. no Sony LMT-300 media block or Sony touch panel) to provide the best in true 4K projection.
The SRX-R320 Series projectors are combined with the Doremi IMB-SA which comprises an
Integrated Media Block unit and separate ShowVault server/storage unit. This system is based on the
Doremi IMB/ShowVault system but customised for operation with the SRX-R320 Series projectors.
The SI-R320S and SI-R320 systems are especially suitable for installations with one or more of the following requirements:
The requirement to combine exceptional, true 4K image quality of Sony digital cinema projection with the Dolby Atmos audio system (optional license is required for IMB-SA server.
Sony ordering code ATMOS-LIC)
Installations wishing to combine exceptional true 4K projection with greater local storage capacity than the 2TB total/1.7TB usable storage available with the Sony LMT-300 media block. The Doremi IMB-SA provides 6TB total/ 4TB usable storage
Allows cinema operators to introduce Sony’s exceptional true 4K quality projection into cinema complexes where Doremi servers are already installed in other screens. Operators will require minimum training on the newly installed SI-R320 and SI-R320S systems
System naming convention
The model naming convention includes “SI” denoting a System Integration solution and contains a reference to the SRX-R320 Series projector model used.
The optical performance of the SRX-R320 Series projectors are directly comparable for 2D projection but if the system is to be used for 3D projection, the appropriate model must be selected for optical compatibility with the 3D filter technology to be used:
The SRX-R320S is optically compatible with the Sony 3D polarising system
The SRX-R320 is optically compatible with the RealD 3D system

2. System overview
The diagram below shows key elements for a simplified overview of the SI-R320 system (please see later for full connection details).
The Doremi ShowVault server/storage unit plays DCI JPEG200 DCPs into the Doremi Integrated
Media Block (IMB) via a PCI-e cable. The IMB unit is installed within the FIPS protected zone of the projector chassis. The IMB carries out DCP decryption, separation of image and audio data and decoding of the compressed image data. The Doremi IMB is customised with LVDS connections to transfer image data to the projector head using the appropriate Sony image data format. The IMB-SA system includes a 4K license allowing full quality playback of 4K DCPs and well as 2K DCPs.
The SRX-R320 Series projector displays full 4K quality using a 2D lens as well as 3D at its native 2K resolution using a separate dual lens if the auditorium is to have 3D capability.
The appropriate model of 2D and 3D lens must be selected to match the auditorium throw ratio
When planning a 3D auditorium, the appropriate model of SRX-R320 Series projector must be selected for compatibility with the intended 3D filter technology to be used.
.
The Doremi server system is controlled by the projectionist via a 15” touch screen or controlled by the cinema TMS via a network connection.
A network switch provides connectivity between the ShowVault server control, IMB unit, projector head, GPIO module and audio processor unit.

3. Key Selling Points
Sony’s true 4K projection and 4K integrated media block
The SRX-R320 Series projectors provide true 4K projection that conforms to the DCI specification, with 4096 x 2160 pixels (four times the resolution of 2K and HD). The combination of an f2.5 large aperture 2D lens made from ELD (Extra Low Dispersion) glass and 4K SXRD imaging chip provides unrivalled true 4K images. The Doremi IMB-SA includes a 4K license allowing full resolution playback of 4K DCPs
Increased local storage capacity
The Doremi IMB-SA system includes the ShowVault-4 server providing approx. 4TB usable storage (6TB total) for installations requiring the facility to hold a greater number of movies for greater flexibility to show different movies programmes for the morning, afternoon, evening and late shows
Optional Dolby Atmos capability
The Doremi IMB-SA offers the option to add a Dolby Atmos playback license (Sony ordering code ATMOS-LIC).
Easy-on-the-eye Sony 3D performance with no flashing
Sony’s unique dual lens system displays 3D movies at their native 2K resolution. The dual lens combined with 3D technology projects the Left and Right eye images simultaneously to achieve crisp 3D images, giving none of the flashing issues associated with systems that use
“triple flash” 3D image technology.
Familiar Doremi GUI
Control of the SI-R320 and SI-R320S systems uses standard Doremi GUI
’s customised to add control of the Sony SRX-R320 Series projectors. Minimum training will be required for staff in cinema complexes with other Doremi server systems already installed

4. Description of key system components
4.1 SRX-R320 Series projectors
Sony has established itself as the leading supplier of 4K projection systems thanks to the SRX-R320P and SRX-R320SP systems where the P = Package including projector, media block and touch panel.
The SI-R320S and SI-R320 projection systems utilise the SRX-R320S and SRX-R320 projector-only models. The performance of these two models is directly comparable except for the optical performance when used with 3D polarising technology. The choice of projector model depends on which 3D system will be used; the SRX-R320S for compatibility with the Sony 3D polarising system and the SRX-R320 for compatibility with RealD 3D.
The SRX-R320S and SRX-R320 operate with standard projector head firmware when used for the SI-
R320S and SI-R320S implementations i.e. no special projector firmware is required.
The table below summarises some of the key features:

4.2 Doremi IMB-SA
The Doremi IMB-SA system comprises an Integrated Media Block (IMB) customised to integrate with the Sony SRX-R320 Series projectors together with a ShowVault server/storage unit.
(1) IMB unit
The IMB unit comprises the Doremi IMB board together with an LVDS converter board to allow the image data to be input to the SRX-R320 Series projector and a power supply unit.
These components are housed in a chassis identical in size and shape to the LMT-300 Sony media block to allow the Doremi IMB unit to be installed in the security cavity of the Sony projector. Though the IMB unit carries an “IMB-SA” logo on the front panel, the name IMB-SA refers to the overall IMB/ShowVault system
The IMB unit has two pairs of LVDS output connectors, meaning it has the ability to output image data to two separate projector heads. However, with the SI-R320S and SI-R320 systems, only one pair of LVDS output connectors are used to feed image data into the single projector head. A pair of
‘LVDS terminator connectors’ (supplied with IMB unit) are fixed to the second pair of LVDS output connectors as shown in the picture below.
The IMB unit also has two Cavity Security System (CSS) connectors. One is connected to the projector
’s security switch circuit which feeds back confirmation that all projector panels are in place to maintain the FIPS security condition required by the DCI. A
‘CSS terminator connector’ is connected to the second CSS connector. The CSS terminator is supplied with the IMB unit.
(2)
ShowVault
The SI-R320S and SI-R320 utilise the ShowVault-4 (4U high) version to provide 6TB total configured on 3 x 2TB HDDs and giving approximately 4TB usable storage.

ShowVault-4 storage supplied in the IMB-SA system utilises 3 x 2TB HDDs for a total of 6TB with approximately 4TB usable storage. This is the maximum system capacity.
The chassis has a 4 th
HDD slot which holds a blank HDD carriage (lower position).
The HDDs carry a label A, B and C to correspond to slots in the ShowVault chassis. Be sure to install each HDD in the correct slot.
The ShowVault stores DCI JPEG2000 MXF wrapped DCPs (and MPEG2 DCPs) using RAID 5 protection. The ShowVault connects to the IMB unit via PCI-e cable for transfer of content.
GUI control of IMB-SA
Projectionist operational control of the SI-R320 and SI-
R320S systems is via a 15” touch panel. The touch panel connects to the ShowVault server and controls the IMB-SA using standard Doremi GUI control screens with the addition of several new control screens which are a customisation to operate the Sony projectors.

4.4 Doremi customised GUI
Operation of the IMB-SA cinema server uses the standard Doremi GUI and menu structure for Ingest,
SPL, Scheduling operations etc. but with additional, customised, menus for operation with the SRX-
R320 Series projectors
4.4.1 Marriage Tool
The standard Control Panel screen of the Doremi has an additional Marriage Tool menu option. This initiates the Marriage (security) process between the Sony projector and Doremi media block.
The Marriage Tool is initiated during installation and during some maintenance procedures involving the removal of panels.
The security process involves two key parts:
1. Cavity Security System (CSS) confirms all projector security doors are closed
2. Marriage communication between security modules in projector and media block ensure the system is not compromised before allowing playback of content (whether encrypted or unencrypted).
The ‘Marriage Utility’ box is a Marriage activation status screen which lists each criteria tested by the security system and the current status of each security check point.
The example screen (right) shows all security criteria have been met and Marriage between the server and projector head is active.

9. Appendix
9.1 4K Resolution (4096 x 2160) pixels
Sony Digital Cinema 4K projectors deliver true 4K resolution which is the highest image quality standard defined by the DCI specification.
An increasing number of cinematographers are choosing to digitise their film negatives at 4K during the movie post production process to capture every detail in the film image. Additionally, an increasing number of leading movie makers are choosing to shoot with the new generation of 4K digital cameras such as the Sony F65.
When the final movie file is released as a 4K DCP (Digital Cinema Package file) instead of 2K DCP and exhibited on a 4K projector, then this super fine detail is preserved from camera right through to cinema screen and the cinema audience gets to enjoy exactly the same experience as the director and cinematographer.
Extremely high native resolution enables the accurate display of the very highest resolution pictures to create more realistic images.
Small pixel size combined with small gaps between the pixels are critical to creating realistic images, especially where audiences will be very close to the screen such as in auditoriums with Stadium style seating. For any given screen size, pixels from Sony 4K projectors are approximately ¼ the size of the pixels from 2K projectors to allow more detail to be displayed and make the pixel structure of the projector invisible to the audience.
Stadium seating brings audience closer to the screen

4K resolution offers additional benefits for movies distributed in 2.39:1 format.
2K is often regarded as being (2048 x 1080) pixels but this is a maximum figure and real movies are distributed as 1.85:1 Flat at (1998 x
1080) active image pixels and 2.39:1 Scope at
(2048 x 858) pixels - which means the vertical resolution in Scope is less than HDTV format images which are (1920 x 1080) pixels.
4K images in both Flat and Scope formats are always well above the resolution of HDTV regardless of image format and always offer much greater detail than the best HDTV pictures.
9.2 Easy-on-the-eye single-projector 3D performance
Due to the high data rates involved, 3D movies are always released at 2K resolution. 3D movies are not released as 4K DCPs.
This allowed Sony to take a new approach to single-projector 3D presentation by utilising the ultrahigh resolution of its SXRD 4K image display panel.
The most commonly used single-projector solutions for cinema utilise the
‘triple-flash’ technique to project the Left and Right eye images in succession through a single lens. This involves taking the Left and Right eye images for each movie frame and repeating them alternately at three times the server playback rate during the projection process. The x3 increase in display frame rate is chosen to be at a high enough level that the viewer should not perceive the flicker between alternating Left and Right eye images out of the same lens. The process requ ires the viewer’s brain to do the work to integrate the rapid, alternating display of Left and Right images into a single image.
The Sony single-projection solution for 3D uses a unique dual lens to simultaneously display both Left and Right eye images on the screen. The viewer is presented with the Left and Right eye images overlaid so the brain is not required to work to integrate two images together as with the triple flash system.
The Left and Right images from the 3D content are simultaneously displayed at their native 2K resolution (2048 x 1080 pixels) on the 4K SXRD display panel at their native frame rate of 24 frames per second. The dual lens projects and converges the two images on the screen for Easy-on-the-Eye
3D.
